In this article, a new design of a compact printed rectangular antenna for wireless local area network (WLAN) applications in 802.11a is investigated. The defected ground structure (DGS) technique is successfully used to reduce the ground plane by cutting a large slot to achieve significant miniaturization. The ground plane structure consists of inverted ‘L’ shape. The rectangular radiating element...
A wideband rectangular patch antenna is presented and experimentally investigated in this paper to covering X- and Ku-Bands. The results are given in terms of the reflection coefficient, and the radiation pattern, and the realized gain. The simulated and experimental results are in agreement. The measured result shows that the wideband antenna works around two resonant frequencies of 11.073 GHz and...
In this paper, we proposed an annular dielectric resonator antenna loaded with printed monopole antenna for a tri-bands application. The results are given in terms of the reflection coefficient, the radiation pattern and the realized gain. Before loading the dielectric resonator, the broadband monopole antenna works around a resonant frequency of 2.704 GHz and can cover a spectrum of 2.1 GHz. However,...
In this work, a compact rectangular monopole antenna is constructed. The results are given in terms of the reflection coefficient and the radiation pattern. The experimental result shows that the narrow band antenna works around resonant frequency of 5.065 GHz and can cover the spectrum of 272 MHz between 4.926 GHz and 5.198 GHz. The size of the proposed antenna with a slotted-feed line and a Defected...
In this communication, we propose a miniaturized rectangular dielectric resonator antenna (RDRA) for wireless communication services (WCS). The studied structure consists of a rectangular Dielectric resonator stacked on a thick layer of dielectric material that has very high permittivity. The numerical analysis was done by two different electromagnetic modeling software; Ansoft HFSS and CST. The obtained...
